Location Requirements
The 24Q and 48Q Ark Tape Libraries require the following environmental conditions:
Criteria Definition
Rack requirements Standard 19-inch rack with vertical space of 2U available for the Q24 or
vertical space of 4U available for the Q48.
Room temperature 10-35°C (50-95°F)
Power source AC power voltage: 100-127 VAC; 200-240 VAC
Line frequency: 50-60 Hz
Place the library near to an AC outlet.
The AC power cord is the library's main AC disconnect device and must
be easily accessible at all times.
Air quality Place the library in an area with minimal sources of particulate
contamination.
Avoid areas near frequently used doors and walkways, stacks of
supplies that collect dust, printers, and smoke-filled rooms.
Excessive dust and debris can damage tapes and tape drives.
Humidity 20-80% relative humidity non-condensing
Clearance Back: Minimum of 15.4 cm (6 inches)
Front: Minimum of 30.8 cm (12 inches) - for mailslot
Minimum of 60 cm to remove magazines (24 in)
Sides: Minimum of 5.08 cm (2 in)
For further information, see "Chapter 7: Specifications" on page 103 .
Serial Attached SCSI (SAS) Requirements
High quality SAS cables rated at the transfer rate of the SAS drives are required.
Always verify that the SAS cable you are using is rated for the data transfer speed
of the interface of your components. SAS cables described as "equalized" may
not support 6 Gb/s data rates and should not be used with LT0-5 or later
generation tape drives without first verifying that they are suitable for 6Gb/s
data rates.

The library has a mini-SAS connector on each SAS tape drive. Mini-SAS connectors are
keyed.

Serial Attached SCSI (SAS) is a computer bus technology mainly used to transfer data to and from
storage devices, including disk drives and tape drives. SAS is designed to transfer data at up to 6
gigabits per second.
